CAR-WHEEL.

SPECIFICATION forming part of Letters Patent No. 439,670, dated.November 4, 1890. Application filed May 26, 1890. Serial No. 353,175.(No model.)

To all whom it may concern.-

Be it known that I, ALFRED MAYER, a citizen of the United States,residing at Phillips burg, in the county of Centre and State ofPennsylvania, have invented certain new and useful Improvements inOar-Wheels; and I do hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to an improved axlebox for car or truck wheels, andhas for its object to provide a device of the character described thatshall be cheap, simple, and durable in construction, one in which theparts are easily assembled, and one that when properly arranged andoiled requires very little attention.

With these objects in View my invention consists in the peculiarconstruction of parts and their novel combination or arrangement, suchas shown in the accompanying drawings, and more fully explainedhereinafter.

In the drawings forming apart of this specification, Figure lis aperspective view of a wheel provided with my improved box. Fig. 2 is aVertical longitudinal section of the box. Fig. 3 is a view showing theseveral parts detached.

In carrying out my invention I employ a hub-section A of iron or othersuitable materiahwhich is provided with abore a, the surface of whichbore is provided with two grooves a, which start from a common pointnear the forward end of the bore and pass spirally to the rear end,where they end in a common point.

Upon the exterior of the hub section, near its rear end, is formed anannular flange B, the forward face of which is perpendicular with theaxis of the bore. A lug O is arranged a short distance forward of theflange and provided with a perpendicular rear face and an inclinedforward face, the purpose of which will appear farther on. The forwardend of the hub-section is reduced at a and around said reduced portionis placed the packing-ring D.

E indicates loops arranged upon the exterior of the hub-section aboutmidway its ends, transverse to its longitudinal axis, and beneath saidloop is placed a fiat spring F, said spring having perforations f nearits opposite ends. One of the perforations fits over the lug C, the endof the spring bearing against flange B, and the opposite end of thespring projects beyond the forward shoulder of the hub. Directly beneaththe spring the hub is recessed, as at c.

G indicates a cap provided with a central opening g, the edges of saidopening being pressed inwardly, as shown, forming ateat g. The rearedges of the cap are provided at diametrically-opposite points with therearwardly-projecting spring-catches H. Said catches being adapted toenter the recess a and engage the forward perforation of the spring F.The peculiar shape of the cap provides a reservoir for the oil, which isfed in through the aperture g, and by means of the spiral grooves theoil is carried to the rear of the box by one groove and to the forwardend by means of the other groove, so that there is always a circulationof oil, no matter which way the wheel revolves. The packing-ringDprevents the escape of oil.

The operation and advantages of my improvement are obvious to every oneskilled in the art to which it pertains.

Having thus described my invention, what I claim is- 1. In an axle-box,the combination, with a hub-section, of a cap-piece provided withcatches adapted to be engaged by springs on the hub-section,substantially as set forth.

2. In an axle-box, the combination, with a hub-section provided withinterior grooves, and with exterior leaf-springs, of a cap provided witha perforated teat and with catches adapted to be engaged by the springson the hub, substantially as and for the purpose set forth.

3. In an axle-box, the combination, with a hub-section, of leaf-springssecured thereto and perforated at their forward ends, the cap-sectionconstructed as described, and the spring-catches adapted to engage theperfo- In testimony whereof Iaffix my signature in 10 rations in thesprings, substantially as depresence of two Witnesses. scribed.
